Observation 168912: Amanita “sp-T06”
When: 2014-06-12

Notes: Found in the Big Sandy Creek Unit of the Big Thicket National Preserve.
Growing singly in mixed woods.
Caps up to 5.5 cm across, somewhat zonate with striations ~ 35-40% of the cap radius.
Spore print was white and spores not amyloid.
Spores ~ 9.2-13.3 X 9.0-13.3 microns, globose to subglobose and smooth.
Q(range = 1.00-1.12. Q(ave) = 1.04.
These look similar to MO#168179 and perhaps Amanita sp-T06.
I’m getting some larger spores but the coloring, cap and stipe features look very similar.

This material is genetically distinct from Amanita justicei.

Hence, it is belongs to one of the two genetically defined groups of specimens that remain for the moment in sp-T06. Why leave them both there? Because we don’t have enough supporting evidence from other material called “sp-T06”. A list of all such material is already in the queue of material to be sequenced. With any luck, we will learn more about how sp-T06 should probably be subdivided. With all the other taxa contesting for sequencing time, this will take a while. We are looking for more sequencing capacity to address the problem.

Very best,


Thanks Ron,

This material has been accessioned and scheduled for DNA sequencing.

The dried material has arrived in Roosevelt.

Thank you very much.

These are now in the competent hands of the USPS.

Very interesting, Ron.

I would like to have look at the material.

Sorry for the short note. I’m rushed today.

Very best,
